One of the most popular legends in the Canary Islands speaks of an eighth island that emerges and disappears near El Hierro and can be seen through the blanket of clouds in Tenerife, La Palma, El Hierro and La Gomera. Medieval cartographers featured it as part of the archipelago in their maps, and its was even believed that it had broken off from the American continent in the past. The origin of this phantom island came from a maritime expedition led by the Irish monastic figure of Saint Brendan in the year 516. He recounted that he had reached an exuberant island of black sand where the sun never set and the trees produced abundant fruit. It was long believed that the island was Paradise.
